Last Friday, Google's John Mueller (JohnMu) posted a strong warning in Google's Webmaster support forums:

I would strongly recommend not using meta refresh-type or JavaScript redirects like that if you have changed your URLs. Instead of using those kinds of redirects, try to have your server do a normal 301 redirect. Search engines might recognize the JavaScript or meta refresh-type redirects, but that's not something I would count on -- a clear 301 redirect is always much better.
